Application filed August 2, 1919.

To all whom it may concern.'

Be it known that I, GEORGE W. yLAN- cAs'rnR, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Windows and Counterbalancing Ventilating Window-Sashes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved window and oounterbalancing Ventilating window sashes, and one of the objects of the :invention is the provision of a window including a plurality of sashes, which are counterbalanced and capable of adjustment whereby thorough ventilation may be per mitted.

A further object of the invention is to provide a main frame and an auxiliary frame, the latter being hingedly mounted in the former, and carrying a plurality of window sashes, whereby partial or 100% ventilation may be permitted.

A further object ofthe invention is to provide a device of this kind in which the wood frames of the sashes are dispensed with and in lieu thereof metal channel pieces.

are substituted, thereby increasing the light area.

A further object of the invention is to reduce the window or hinged frame in thickness, that is, from the usual 6 wide to substantially 2 wide thereby enabling four sashes to be slidably mounted7 using a frame of about 2 wide instead of two sashes, mounted in a 6 wide frame.

A further object of the invention is to eliminate the weight receiving boxes of the window frame, as well as eliminating the weights themselves.

A further object of the invention is to eliminate the moldings, and also to dispense with the usual wooden sash frames.

Obviously when eliminating the weights and sash cords, the usual pulleys are eliminated and in lieuthereof other pulleys are mounted whereby the sashes in the present case may be counterbalanced through the medium of cords passing over said pulleys and connecting to opposite sashes.

A further object of the invention is to provide a window of this character including a main frame and an auxiliary frame, the latter being hingedly mounted in the Specification of Letters Patent.

former, so that it may be swung to a position inwardly of the room, and while in such position, the plurality of sashes, which are counterbalanced, may be raised and lowered.

A further object of the invention is to provide an auxiliary hingedly mounted sash carrying frame including a plurality -of panes mounted in counterbalanced sashes, which are channeled, whereby the panes may be easily and quickly removed.

A further object of the invention is to provide an auxiliary inner frame hingedly mounted in amain stationaryframeincluding guides aiforded by parting strips, which are detachably and removably mounted so that the sashes can be easily and quickly removed subsequent to which the panes can be removed from the sashes.

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view in perspective of the improved window construction showing the plurality of sashes mounted in the auxiliary inner hingedly mounted frame;

Fig. 2 is a view in elevation of the window showing the sashes adjusted centrally of the inner auxiliary frame, whereby thorough ventilation is permitted above and below the sashes;

Fig. 3 is a vertical sectional view on the line 3--3 of Fig. 2, but showing the sashes adjusted in the upper and lower parts of the inner auxiliary hingedly mounted frame, whereby thorough ventilation is permitted between the sashes;

Fig. 4 is an enlarged detail sectional view on the line 4wd of Fig. 1 of the upper part of the inner auxiliary frame showing the mounting of the casting which carries one set of the upper pulleys over which the cords of the sashes pass;

Fig. 5 is a vertical sectional view on the line 5 5 of Fig. 4, showing one of the pulleys of one of the upper series, showingl the cord connected to one of the sashes and passing over the pulley; i

Fig. 6 is an enlarged transverse sectional view on the line 6-6 of Fig. 1; and

F ig. 7 is an enlarged detail perspective view of a joint between one of the upper rails of the inner hinged frame and one of the side rails of said frame, showing the opening for the reception of the casting which carries one set of the pulleys.

Referring more especially to the draw'- ings, 1 designates a portion of a wall of a house or dwelling, having the usual opening 2 formed therein, adapted for the reception of a window frame. However, in lieu of the usual window frame, a differently designed frame 3 is mounted in said opening. This frame 3 comprises a vertical longitudinal side 4i, and the upper lowei1 end pieces 5. Secured in any suitable manner to the inner face of the wall 1 adjacent the margin 'of the opening 3 is a wood trimming 6, thereby presenting a neat appearance.

An auxiliary inner sash carrying frame 7 is hingedly mounted as at 8 in the main frame, and when in a. closed position it engages a jamb 9. This jamb is formed by the vertical and horizontal strips 10 which are secured to the inner side faces and the upper and lower faces of the main frame.

Secured to the inner side and upper and lower faces of the auxiliary frame by means of suitable screws 11 are parting strips 12. These strips 12 are spaced as shown, thereby providing guides 13 for the window sashes 14. These window sashes 14 are constructed of sheet metal in the form of channels. ln fact, the sash frames may be constructed of sheet aluminum, or preferably sheet steel1 though not necessarily, for it is obvious that brass or nickel plated metal may be used. However, sheet steel has been found most desirable for this purpose, and these sashes 14 receive the window panes 15. The sashes extend about the lower and end edges of the window panes, as shown, and portions at the upper end pieces of the sashes are provided with bent over tongues 16 having apertures 17. Suitable cords or cables are attached to the tongues 16. 'In fact, the ends of the cords or cables are passed through the apertures or openings 17 and are knotted or provided with other enlargements to hold the cords fastened.

In the present instance, there are four sashes employed., though not necessarily, for any number of sashes may be used, say for instance, six, eight or ten, it depending upon the size of the window to be constructed.

The upper rail 18 of the inner auxiliary frame has its ends bifurcated as shown at 19 to be engaged by the contracted portions 20 of the side vertical rails 21. Suitable screws or other fastening means pass through the forks 22 which are caused to be formed by the bifurcations 19 and into the contracted portions 20 of the side rails 21, thereby securing the side rails 21 to the upper rail.' It is to be noted that the bifurcations 19 are deep enough, eventhough the contracted portions v20 aresecured therein, to re eive the metal castingsr 2S which carry a plurality ofpulleys 24 and 25. These castings 23 are secured in the space afforded by the bifurcations 19, as shown at 26. y i

Passing over the pulleys 24.- and connected to the tongues 16 of the innermost sash and to the tongues 16v of the outermost sash, are cords or cables 27. Passing over the pulleys 25 and connected to the tongues 16 of the next inner and outer sashes, are cables 2S.y lt will be noted that by means of these cables 27 and 28, the innermost and outermost sashes and the next innermost and outermost sashes are counterbalanced, hence making it possible to adjust all of the sashcs centrally of the .inner auxiliary hingedly mounted frame, as shown in Fig. 2 or the two innermost sashes in raised positions and the outermost sashes in lowered positions, as shown in Fig. 3, Furthermore it is possible to adjust all of the sashes 'in entirely closed positions as shown in Fig. 1. lf necessary, the outermost sashes may be raised together, to uppermost lpositions with their tops `in horizontal planes relatively, while the innermost sashes may be lowered together. Also the sashes be adjusted in other desirable positions to attain ventilation.

lt is obvious that the inner auxiliary can be swung inwardly of the room so that 100% ventilation is permitted. lhile the inner auxiliary frame is in such position, inwardly of the room, it is possible to raise and lower the sashes at'will to any desired positions, so that the panes of glass may be thoroughly cleaned.

The tongues 16 of the sashes may be bent to vertical positions and subsequent Vto hav- .ing detached the cords or cables therefrom the window panes may be easily removed.

liiowever, this is only necessary when a pane' it may be lockedy or latched in any suitable manner, as shown'at 29. vThese locks or latches may be of any suitable construction, and the outer flange of the low'errail of each sash has ya horizontal extension flange 30. These extension flangesare designed to engage the bars 14a of the upper parts of the sashes when they are in closed positions, as shown in Fig. 1, thereby preventing the air or wind from passing into the room.

In order to aord a closed joint between the extension flanges 30 and the upper parts of the sashes, the upper ends of the side stiles of the lower and innermost and intermediate sashes on their outer sides thereof are provided with connecting pieces 14a with which the extension flanges 30 engage when all the sashes are closed.

rlhe invention having been set forth what is claimed as new and useful is l. In improvements in a window st ructure, a window frame, a main sashswlngingly and operatively mounted in the main frame and provided with guides, upper outermost and lower innermost sashes mounted in certain of the guides and operatively connected, one counterbalancing the other whereby the movement of one simultaneously operates the other, intermediate auxiliary sashes operatively connected and counterbalanced whereby the movement of one causes the operation of the other, said auxiliary sashes when in their closed positions being offset in stepped relation, the lower rails of the uppermost sash and the lower rail of each of the intermediate sashes having extension flanges coperating with the upper parts of the adjacent sashes to insure an air tight window closure when the sashes are closed.

2. In improvements in a window construction, a frame, a sash supporting frame operatively and swinginglv mounted in the first frame and provided with guides, upper outermost and inner lowermost sashes having window panes and mounted in certain of the guides, intermediate sashes having panes and mounted in certain other of said guides, said sashes when in closed positions being overlapped in stepped relation, the upper outermost and the inner lowermost and the intermediate sashes being respectively operatively connected and counterbalanced whereby the upper outermost and the lower innermost sashes may be lowered and raised the extreme height of the sash supporting frame' and whereby the intermediate sashes may be interchanged in their positions relatively overlapping each other and the edges of said upper outermost and lower innermost sashes thereby permitting a slight ventilation between the overlapping edges of the sashes.

8. In improvements in a window construction, a frame, a sash supporting frame operatively and swingingly mounted in the first frame and provided with guides, upper outermost and inner lowermost sashes having window panes and mounted in certain of the guides, intermediate sashes having panes and mounted in certain other of said guides, said sashes when in closed positions being overlapped and in stepped relation the upper outermost and the inner lowermost and the intermediate sashes being respectively operatively connected and counterbalanced whereby the upper outermost and the lower innermost sashes may be lowered and raised the extreme height of the sash supporting frame and whereby the ntermediate sashes may be interchanged in their positions relatively overlapping each other and the edges of said upper outermost and lower innermost sashes thereby permitting a slight ventilation between the overlapping edges of the sashes, the lower rails of the upper outermost and the lower rails of each of the intermediate sashes having extension flanges to coperate with the upper part of the adjacent sashes to insure an air tight window closure when the sashes are in their normal closed positions.

4t. In improvements in a window structure, a window frame, a sash swingingly and operatively mounted in said frame and provided with guides, upper outermost and lower innermost auxiliary sashes operatively mounted in certain of the guides, the former adapted to assume an upper normal position, the latter to assume a lower normal position, said auxiliary sashes bein operatively connected and counterbalance whereby the former may be lowered and the latter raised the full height of the swingingly mounted sash, intermediate auxiliary sashes operatively connected and counterbalanced and being adjustable relatively to the other sashes for partially or entirely closing the space between said other sashes.

5. In improvements in a window structure, a window frame, a sash swingingly and operatively mounted in said frame and provided with guides, upper outermost and lower innermost auxiliary sashes operatively mounted in certain of the guides, the former adapted to assume an upper normal position, the latter to assume a lower normal position, said auxiliary sashes being operatively connected and counterbalanced, whereby the former may be lowered and the latter raised the full height of the swingingly mounted sash, intermediate auxiliary sashes operatively connected and counterbalanced and being adjustable relatively to the other sashes for partially or entirely closing the space between said other sashes, the lower rails of the upper outermost and the intermediate sashes having extension flanges cooperating with the adjacent sashes when all the sashes are closed, thereby providing an air tight window closure when the sashes are entirely closed.

In testimony whereof I hereunto aliix my signature.
